Míriel Serindë, also spelled Þerindë, ("The Broideress" in Quenya) was the first wife of Finwë, King of the Noldor. Her son was Curufinwë, whom she called Fëanor, which means "Spirit of Fire". Miriel's hair was described as being silver in appearance, an unusual color for one of the Noldor.

After giving birth to Fëanor she wished to die, saying that the birth had taken much of strength and spirit. Her fëa departed from her body, and she entered the Halls of Mandos. In essense, she had died of free will. This was seen as a shocking event by the Valar, and Manwë allowed Finwë to take another wife.

After Finwë had been killed, Míriel was granted permission to return to life, where she entered the service of Vairë, her task to weave all the deeds of the House of Finwë in the Tapestry of Time.

Other versions of the legendarium

The Shibboleth of Fëanor is a story where Fëanor is a grown person, however Míriel is still alive, to whom he talks about his concerns. In the published Silmarillion, Míriel died soon after birth.
